All people fail us. At one point or another, each person betrays the bond that they have made with us. This is not an excuse to cut off our relationships, though. It is still right and prudent to invest in people and relationships. But to protect our soul against heartbreak, we must also develop even stronger bonds to the ideal and the transcendent, which will never fail us. Just as we have a relationship with people, we can, and must, have a relationship with each of the virtues. And then we remain committed to the relationship, not just for the person, but for the ideal’s sake.

So,

Become married to the ideal of marriage
Begin a romance with romance
Be a friend of friendship
Fall in love with love
And be loyal to loyalty
